Selecting the material to be used from various materials is a work restricted by many factors. Therefore, how to choose the material of the part is an important part of the part design. The principle of selecting materials for mechanical parts is: that the required materials should meet the requirements of the parts and have good manufacturability and economy.

Precision parts processing produces parts from materials and processes, which are very precise processes. The workpiece processing requirements in precision machining generally require precision machining of parts in the form of numerical control.

For parts with complex designs, most manufacturers will ask for 3D files. Compared with 2D plane drawings, 3D drawings can see the appearance and shape of the workpiece; It is best to add some dimensioning and processing requirements to the 3D graphics to form a display form that integrates 3D drawings and process cards; this will enable us to understand your design intent more intuitively and more accurately give appropriate processing plans.
